MACHINE FOR PACKING SHINGLES AUTOMATICALLY.

SPECIFICATION fern-ling part of Letters Patent No. 424,673, dated April 1, 1890.

Application filed August 2, 1887. Serial No. 245,989. (No model.)

To all whom t may concern:

Be it known that l, HERMAN L. FEHLBERG, a citizen of the United States, residing at La Grosse, La Crosse county, State of lVisconsin, have invented a new and useful Machine for Automatically Packing Shingles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, forming a part of this speciiication, and to letters of reference marked thereon.

This invention relates to that class of machines which pack shingles as they are fed in, (after being jointed,) it being easy to manipulate and perfectly automatic in operation.

The object of this invention is to save the time and labor usually spent in packing shingles by hand, which object l have attained by the means illustrated in the accompanying drawings.

Figure l is a sectional View of my machine on the line A A of Fig. 3. Fig. 2 is a similar view taken on the line B B of Fig. 3. Fig. 3 is a side elevation of the machine. Fig. 4: is a top plan view. Fig. 5 is an elevation of the side opposite that shown in Fig. 3. Fig. 6 is a detail view of the shaft G and clutch thereon, and Fig. 7 is a sectional view taken on the line C C of Fig. 3.

Similar letters refer to similar throughout the several figures.

Referring to the drawings, E indicates the main driving-shaft, Fig. 3, and upon said shaft there is mounted a worm-gear E', pulleys S2 and S5, and friction-Wheel F. The wheel F is thrown in and out of contact with F by a lever working in L, for a purpose hereinafter named. W'orm-gear E', Fig. 7, drives shafts P P P2 P5 and also clutches H and U. The clutches lll and U are loose on shafts G and O and revolve freely on same. The shafts O and G have slots J2, as shown in Fig. 7, in which a key works, as shown in Fig. 6. I have given the side section in Fig. 6, and in Fig. 7 the top section of slot, key, and lug of shafts G and O. The said keys, on which clutches H and U2 are fastened, have lugs on one side, as shown in Fig. 6 at L2. Collars L4 and U7 are made to bear on these lugs by parts springs K5 and U5, which are kept tight by the cams K and O. The collars L3 and U5 are fastened to shafts O and G. Vhen lever K,Figs. 2 and 3, is disengaged from between lug L2 and collar U5, spring U6 will force clutch U2 in gear, and shaft O will make one turn, when lever K, having dropped back, will throw clutch U2 out, and shaft O will stop. Shaft G, Fig. 6, works on the same principle, collar L3 keeping clutch Hin place. The clutch U on shaft. O is held in place by sleeve J5, Fig. 7, and collars J 5 and J4. Sleeve J5 has a set-key, on which Works clutch U', being thrown in and out of gear by a lever L7. On sleeve J5 is fastened a gearUS, which drives shafts U4, on which is fastened rolls S, carrying belts SJi and S5, Fig. 4:.

Belts S5, Fig. 4, have cleats fastened on at suitable distances for carrying shingles out of feed-boxes lll and M2, Fig. 3, where they are to be piled in butt-end toward the outside of machine, as shown in Fig. 2. These boxes have an opening on the side at the bottom toward the way belts S5 travel, which is a little larger than the size of shingles, thus allowing cleats on belts S5 to carry shingles through this opening single. Said shingles are then deposited on belts S4, which carry them along and shove them on ily T2, for a purpose hereinafter described.

The saw-frame Q, Fig. 2, is moved back and forth by crank J, which is 'fastened 011 shaft G and is held in place by guides Q and Q2. Saw S is run by pulley S2 and belt, as shown, through tightener R and cord R', slack being taken up by weight R2 when sawframe Q, passes back and forth. The sawframe Q and shaft G are under control of lever L2 Z; but when said lever is lifted from between collar L3 and lug L2 shaft G will make one turn, thus working saw-frame Q back and forth once, when said frame Q will stop on left-hand side of machine.

The wheel V, fastened on shaft G and having a notch cut out, as shown in Fig. 7, works on lever V', which in turn works arm V3 through rod V2. Arm, V3 is fastened on a shaft, which works arms V4 up and down through bevel-gears, as shown, for a purpose hereinafter named.

The iy T2 is hollow and connected by trunk IOO 1ot spring V2.

T to fan X, driven by pulley S5, which creates a suction, and this hold shingles on ily T2 while being deposited on car T5. The flyshaft T is worked by pinion C4 and segment O5, being connected by rod, as shown, to crank O2, fastened on shaft C. The segment O is also fastened on shaft O and works lever N,which works N5, geared into N4 on shaft W5, on which ,is pulley W, working-valve W', and This spring shuts suction off when fly T2 is on the point of returning, and thus causing shingles on y T2 to be deposited on car T5. The shaft O8 is driven by shaft VT, Fig. l. Friction-pulley F,with chain-wheel and clutch, as shown, revolves freely on said shaft O8. Clutch O5 is held by set-key on and revolves with shaft O8 and can be thrown out of gear from F by lever L. The chain O5, Fig. 3, drives the wheels, which have threads cut inside and work on O7, running car and table T5 up and down. Vhen F is driven by F and clutch O5 is lifted out of gear by lever L table and car T5 will be caused to run up by chain O5, FigB; but when F is thrown out and O5' dropped in gear table and car T5 will be caused to run down the thickness of a shingle at each half-turn of shaft O5, for a purpose hereinafter named.

T7 is a stop on fly, the distan ce between this and saw S being the exact width and the distance between guides Z' and Z2 being the exact length of a bundle of shingles. Rollers S, Fig. 2, have enough dilference in their diameter so that one row of shingles may pass over the other, and thus secure the lap necessary in bunching shingles.

Z Z are shingles.

Bar T5, Fig. 5, is for V4 to rest on when holding down shingles while saw S is cutting off the width on fly T2.

I is the driving-pulley.

The operation of the above-described devices constituting my shingle-packer'is as follows: Assuming that the driving-shaft E is in motion and that shingles have been piled in feed-boxes M and M2, thick end toward the outside of machine, and that car and table T5 have beenY run up to the proper height, by raising clutch O5 out of'gear from F and forcing friction-wheel F on F will raise car and table T5 through chain O6 and screws O7, and when high enough throw out friction F from F and drop back clutch O5. By setting clutch U in gear with clutch U starts sleeve J 5, and through chain runs rolls S, on which travel belts S5 and S5. Belts S5 have cleats, as shown in Figs. 4 and 5, which take along shingles one at a time from bottom of feed-boxes M and M2 and deliver said shingles on belts S4, which Y on the shingles by wheel V, lever V', rod V2, f

layer, and so on.

and crank V5, as shown. Arms V4 will hold the shingles on bar T6 and fly T2 while saw S is passing from side Yto side. When saw S arrives at theleft-hand side, Fig. 2, lever L2 Z will throw shaft Gr out of gear again. Wheel V, having a notch cut out, as shown,'will allow spring M to pull up arms V4 after shaft G has made one turn. Collar K, with lug having lifted lever K', disengages clutch U2, which allows shaft O to make one tu rn. Crank O2, being fastened on shaft O, will make flyshaft T turn half-way over and back through segments O3 C4 and rod, as shown, shingles being held on by suction created by fan X, air passing in at openings T3 on fly T2, but

covered by shingles when Yfly T2 is loaded.-

Ribs T4 on ily T2 are to support shingles while being carried over and disposed of on car T5. When fly T2 is returning, the cam O on shaft O having opened valve W through lever N, gears Ns N4, shaft W5, with pulley W, will let lever N go and spring W2 will shut suction off, thus causing ily T2 to deposit shingles on carT5 the instant it starts to return. When iiy T2 is returning, bevel-gears on shaftT and Os will cause clutch O5 to turn F far enough so that car and table T5 vwill be lowered the thickness of a shingle, thus making room for next When a certain number of layers are deposited, car T5 is pushed off and the table on which the track lies is raised again and another is pushed on.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
